How can a web app create more instances of engine or same instance of engine can provide multi-threading?

I have a web-app using activiti engine in a mission critical app and process central to company's core business process. It has been running since 2012. Now, it is showing signs of distress under load. As there can be only one engine, how can it be used to serve multiple requests simultaneously? Please, throw some ideas.

"As there can be only one engine" - Is there a particular reason for this? Generally the way you scale activiti based applications is through horizontal scaling.

Yes, like Ciju said, it is interesting to know why you are restricting yourself to 1 Activiti engine? 

Have you looked at these articles/documentations?
